Take A Look At The Unprecedented Shift In Support For Gay Marriage Over The Past Decade

Support for same-sex marriage has undergone a dramatic and unprecedented shift in the past decade, with more people now firmly supporting it than opposing.

The Pew Research Center recently took a look at its polls on the subject from the past 10 years. The key number is the combined 26-point swing over that period. Ten years ago, 57 percent of Americans opposed gay marriage, compared with 35 percent that supported it.

"The change in attitude is certainly unprecedented," said Greg Smith, a senior researcher at the Pew Research Center.

"It's hard to say how any one issue compares with another. One thing to point out would be that in recent polling by our colleagues, whereas attitudes on same-sex marriage have been moving for the past few years, attitudes about abortion, for example, have been more stable," Smith added.
